Abstract

We review here two unique organelles from Trypanosoma cruzi. One of them is the acidocalcisome, cytoplasmic vacuoles containing a very high Ca2+ concentration and a Ca2+ - H+ translocating ATPase activity, present in all trypanosomatids. The other organelle is the reservosome, site of accumulation of endocytosed macromolecules, very rich in cysteine proteinase, that is present only in epimastigote forms of trypanosomes belonging to the Schyzotrypanum sub-genus.

摘要

我们在此综述来自克氏锥虫的两种独特细胞器。其中一种是酸性钙胞器，即细胞质液泡，含有非常高的钙离子浓度以及钙离子-氢离子转运ATP酶活性，存在于所有锥虫目生物中。另一种细胞器是贮存体，是内吞大分子的积累位点，富含半胱氨酸蛋白酶，仅存在于属于裂殖锥虫亚属的锥虫的上鞭毛体形式中。
